Where Idaho's Money Comes From

Idaho state government will spend about $14.4 billion in fiscal year 2027, which runs from July 1, 2026 to June 30, 2027. Most news stories quote a smaller number, about $5.6 billion. Both are right. They measure different piles of money, and a reader who does not know which pile a number belongs to will misread nearly every budget story.

This lesson sorts the piles. It uses the LSO's 2026 Legislative Fiscal Report, which summarizes the budget the Legislature adopted in the 2026 session, and the Governor's July 2026 announcement of how FY2026 ended. Later lessons cover the calendar (lesson 2), who does what (lesson 3), forecasts (lesson 4), holdbacks (lesson 5) and reserves (lesson 6).

Three fund groups

The state runs hundreds of separate funds. The Legislative Fiscal Report squeezes them into three groups for reading, though the appropriation bills themselves cite the specific fund. The glossary defines each group.

• General Fund: money from taxes and certain licenses and fees not specifically appropriated to any other account, used for the general operations of state government.
• Dedicated funds: revenue from a specified source that is spent for a specific function as required by law. The glossary's example is the State Highway Fund, partly paid by motor fuels tax and vehicle registration fees and used for highway construction and improvement. Dedicated funds also include money one agency pays another for services.
• Federal funds: money from the federal government for specified services.

Fund group	FY2027 appropriation ($ millions)	Share of total
General Fund	5,621.8	38.9%
Federal funds	5,404.3	37.4%
Dedicated funds	3,423.6	23.7%
All funds	14,449.7	100.0%

Source: 2026 Legislative Fiscal Report, FY2027 All Appropriations by Fund and Function, page 29. Check the sum: 5,621.8 plus 5,404.3 plus 3,423.6 equals 14,449.7.

Federal and dedicated money together come to $8,827.9 million, which is 61.1 percent of the all-funds total. When a story says "the state budget" it usually means the General Fund, because that is the money the Legislature can redirect. When a story about a specific agency uses an all-funds number, the General Fund share can be much smaller. The Department of Health and Welfare's original FY2027 appropriation was $6,543.6 million. Of that, $1,269.2 million (19.4 percent) is General Fund, $1,387.2 million (21.2 percent) is dedicated and $3,887.2 million (59.4 percent) is federal. A cut to that department's General Fund share and a cut to its all-funds budget are very different sizes.

What the money buys

The same $14,449.7 million can be sliced by purpose instead of by source. The Legislative Fiscal Report groups it by function.

Function	FY2027, all funds ($ millions)	Share
Health and Human Services	6,540.5	45.3%
Education	4,258.3	29.5%
Economic Development	1,678.0	11.6%
General Government	727.5	5.0%
Public Safety	719.7	5.0%
Natural Resources	525.7	3.6%
Total	14,449.7	100.0%

Source: 2026 Legislative Fiscal Report, page 29. The six function amounts add to 14,449.7.

The picture flips when only the General Fund is counted. Of the $5,621.8 million General Fund appropriation, all education is $3,417.6 million (60.8 percent), including $2,750.4 million for public schools (48.9 percent). Health and Welfare is $1,269.5 million (22.6 percent) and public safety is $581.2 million (10.3 percent), according to the report's pie chart on page 28. Health care looks like the biggest item in the all-funds view because federal money flows through Medicaid. Schools look like the biggest item in the General Fund view because they are paid mostly with state dollars.

One note on method. The report's functional total for Health and Human Services ($6,540.5 million) and the single-agency figure for the Department of Health and Welfare ($6,543.6 million) differ by about $3.1 million. The pages checked for this lesson do not explain the gap, so a reporter should pick one definition and say which one was used.

Where General Fund revenue comes from

The General Fund is where the contested choices happen, so its sources matter most. The Economic Outlook and Revenue Assessment Committee (EORAC), a legislative committee of nine senators and nine representatives, reviewed the executive forecast in January 2026 and concluded that General Fund revenues available for appropriation would be $5,665.1 million for FY2026 and $5,816.6 million for FY2027. The Joint Finance-Appropriations Committee (JFAC) used those numbers to set budgets. The Legislature then passed H.B. 559, which conforms Idaho's tax code to federal changes and lowers expected revenue. The table shows the estimate after law changes.

Source ($ millions)	FY2025 actual	FY2026 estimate	FY2027 estimate	FY2027 share
Individual income tax	2,418.9	2,496.8	2,468.1	43.8%
Sales tax	2,079.4	2,273.0	2,430.1	43.1%
Corporate income tax	890.6	462.3	469.7	8.3%
Product taxes (liquor, beer, wine, tobacco, kilowatt hour)	67.0	66.8	66.8	1.2%
Miscellaneous (insurance premium tax, interest, unclaimed property, fees, transfers)	421.4	211.3	204.9	3.6%
Total revenue	5,877.3	5,510.1	5,639.7	100.0%

Source: 2026 Legislative Fiscal Report, General Fund Revenue Collections and Estimates, page 27. FY2026 and FY2027 are estimates "with law changes" from the January 2026 forecast, not final collections. Figures are rounded to the nearest $0.1 million.

Two lines in this table deserve a second look.

First, individual income tax and sales tax together are $4,898.2 million, or 86.9 percent, of FY2027 estimated revenue. A change of one percentage point in either one moves the budget by tens of millions of dollars. That is why the state's economy, wage growth and consumer spending show up in budget stories.

Second, corporate income tax was $890.6 million in FY2025 and is estimated at $462.3 million in FY2026, a drop of $428.3 million. Part of the FY2026 drop is H.B. 559, but the pre-law-change forecast was still only $517.3 million. The pages of the report checked for this lesson do not explain the rest. Corporate tax is volatile because it depends on profits and on how multistate companies apportion income. LSO's 2022 presentation calls it "very volatile." If you write about a swing like this, ask the Division of Financial Management (DFM) for the cause before guessing.

The sales tax, split before it arrives

The sales tax line in the General Fund table is the amount that remains in the General Fund. Sales tax revenue is divided among several recipients under state law before the General Fund gets its share. LSO's 2022 presentation put the FY2022 split of net sales tax revenue of $2,881 million as follows. This is older data, and the distribution rules have changed since, so use it to understand the idea and look up the current formula in lesson 9.

FY2022 recipient	$ millions	Approximate share
General Fund	2,195	76%
Local tax relief and election consolidation	368	13%
Tax Relief Fund	184	6%
State earmarked accounts	133	5%

Source: LSO, Idaho Tax and Revenue Structure, Nov. 29, 2022, page 11. Shares computed from the dollar amounts (2,195 divided by 2,881 is 76.2 percent). The same presentation gives the statewide sales tax rate as 6 percent, first enacted in 1965 at 3 percent, with a local option only for resort cities.

The same presentation lists what the sales tax does not reach, with annual dollar estimates: most services (about $2.6 billion), motor fuels, certain utility sales, prescriptions and durable medical equipment, agricultural production, SNAP and WIC purchases, and purchases by schools, hospitals, governments and charities. It also describes the sales tax as a tax on consumption that is generally regressive, meaning a higher share of income goes to taxable goods for lower earners. That is LSO's description; people who favor a broader sales tax base and people who favor a narrower one both use the same exclusions list in their arguments.

What the state does not collect

Property tax is missing from the General Fund table on purpose. LSO's presentation describes it as the oldest state and local tax, a major source of revenue for local governments and some school districts, and states that the state does not receive revenues from it. Counties, cities, school districts, fire districts and other local taxing districts levy it. Most school districts rely on property tax for supplemental levies and bonds on top of state appropriations.

That matters for two reasons. When a resident says "the state raised my taxes" after a property tax bill arrives, the state did not collect the money, although state law sets the rules, caps and exemptions that shape the bill. And when the state cuts a budget, local governments may or may not need to replace the money through their own levies. Lesson 9 and the course on Idaho property taxes follow that thread, and Local Government lesson 3 shows how a city or county records its own funds.

Why federal money is both large and fragile

Federal funds are 37.4 percent of FY2027 appropriations. Most of it comes with strings: it must be spent on the program the federal government funds, often with a state match from the General Fund. The Department of Health and Welfare is the clearest case, at 59.4 percent federal in FY2027.

Idaho law makes agencies plan for that. Under Idaho Code 67-3502(1)(e), each agency's budget request must include a report disclosing any known future reductions or eliminations of federal money and the agency's plan for operating if its federal funding falls by 10 percent or more. Part IV of the Governor's executive budget carries the federal funding reports (67-3507). A reporter looking at a budget request can check that section to see what the agency itself says is at risk.

Federal money also moves the General Fund indirectly. The Legislative Fiscal Report notes that the FY2027 General Fund appropriation for Medicaid rose by $53.8 million even after provider rate decreases, because of population growth, and that the Department of Correction had mandatory growth too. These are the "non-discretionary" areas that DFM's budget director has cited as absorbing most of any projected revenue increase (lesson 3 and lesson 5 return to this).

Forecast versus what actually arrived

Everything above for FY2026 and FY2027 is an estimate. The Governor's office reported on July 17, 2026 that FY2026 General Fund revenue came in about $171.9 million above DFM's revised forecast and about $19.2 million above the Legislature's forecast, that about $250 million in cash would carry into the FY2027 General Fund, and that the Idaho State Tax Commission issued more than $910 million in individual income tax refunds in the fiscal year, the most ever in one year. The release says Moody's reaffirmed Idaho's AAA rating with a stable outlook.

Notice what that does and does not say. "Above forecast" depends on which forecast. The DFM revised forecast was lower than the one the Legislature adopted, so beating DFM's by $171.9 million and the Legislature's by $19.2 million are both true at once. A fair story names the forecast it compares with. The early FY2027 months follow the same pattern: the Idaho Capital Sun reported on October 9, 2026 that September revenue was $39 million (7 percent) above DFM's projection and that the first three months of FY2027 were $90.3 million (6.8 percent) above, with individual income tax running ahead and corporate income tax behind. Three months do not make a year, and lesson 4 shows how to read the monthly report yourself.

Questions and answers

Why do some stories say $5.6 billion and others $14.4 billion?

The first number is the General Fund appropriation for FY2027 ($5,621.8 million). The second is every appropriation from every fund ($14,449.7 million). Neither is wrong. A good story names which one it uses.

Is the General Fund the only money the Legislature controls?

No. The Legislature appropriates dedicated and federal funds too, and the appropriation bills cite the specific fund. But it has the most room to redirect General Fund dollars, since dedicated and federal money often comes with legal limits on its use.

What is the difference between revenue and an appropriation?

Revenue is money coming in. An appropriation is permission to spend. The Constitution says money leaves the treasury only under appropriations made by law (Article VII, section 13), and the Legislature may not authorize spending above the tax provided by law (section 11).

Why does the revenue table have an "FY2025 actual" column and "estimate" columns?

FY2025 closed on June 30, 2025, so its number is collected cash. FY2026 and FY2027 were still forecasts when the Legislature adopted the budget in the spring of 2026. FY2026 has since closed, and the Governor's July 17, 2026 release reported how it came in relative to the forecasts.

Where does the money for roads come from?

Largely from dedicated sources. The Legislative Fiscal Report's glossary uses the State Highway Fund as its example of a dedicated fund, supported partly by motor fuels tax and vehicle registration fees and spent on highways. It sits outside the General Fund table.

Do grocery credits, tax rebates and other tax changes show up in this table?

Tax changes show up as reductions in the revenue line when a bill lowers collections, as H.B. 559 did. Lesson 7 covers the major tax bills and what their fiscal notes say they cost.

Can a resident look at the same documents the Legislature uses?

Yes. The Legislative Budget Book, the Legislative Fiscal Report, the Fiscal Sourcebook and Fiscal Facts are public on the LSO site. Lesson 10 shows how to use them.

Is the income tax rate in this lesson?

No. This lesson is about shares and dollars. Rates have changed several times in recent sessions and lesson 7 covers them with the fiscal notes. The Idaho State Tax Commission's site is the place to confirm the rate for a given tax year.

Hard questions

"Idaho cut taxes and then cut budgets. Did the tax cuts cause the shortfall?"

People who study the numbers describe it differently. DFM Administrator Lori Wolff told the Idaho Capital Sun in November 2025 that DFM calculates the tax cuts since 2019 reduce revenue by about $900 million a year and about $3.2 billion cumulatively; the Idaho Center for Fiscal Policy puts the five-year total near $4 billion. Legislative Democrats argued during the 2026 session that the Legislature created its own shortfall through income tax cuts. Republican leaders said the 4 and 5 percent budget cuts guarded against revenue uncertainty and paid for federal tax conformity. The Governor's July 2026 statement credited fiscal discipline for the year's outcome. The revenue arithmetic in the table is common ground. The disagreement is over priorities and over how to weigh economic growth against lost revenue, which lesson 7 explores.

"Why does Idaho depend on income and sales taxes for 87 percent of its General Fund?"

Those are the two largest taxes the state collects, and the property tax is left to local governments. Supporters of that arrangement point to the stability and accountability of keeping property tax local. Others point to the volatility of income taxes during downturns and the regressive character LSO attributes to sales tax. Both descriptions come from the same sources. The structure is set by the Legislature and could be changed by it.

"If federal money is 37 percent of the budget, does the Legislature really control it?"

The Legislature appropriates it, but federal law largely decides how it can be used and whether it continues. That is why Idaho Code 67-3502(1)(e) requires agencies to plan for a 10 percent federal reduction. A cut in federal money may or may not lead to General Fund replacement, and that choice falls to JFAC.

"A forecast beat the estimate by $171.9 million. Why were agencies still cut?"

The Legislature set the FY2027 budget in the spring using the January forecast, before FY2026 closed. Officials quoted in the Capital Sun's July 2026 coverage expected tight budgets to continue into FY2028 and did not anticipate more holdbacks, with any additional revenue going first to employee pay, delayed transportation projects, schools and wildfire funding. Critics of the across-the-board cuts said they were applied to agencies regardless of need (the Capital Sun reported that legislators from both parties and some agency directors made that point), and Sen. Kevin Cook said that rolling the cuts into one 50-page rescissions bill made them hard for the public to trace. Supporters said the cuts were a hedge against revenue uncertainty. Both positions are on the record in the 2026 session coverage.
